I don't really like piling on, but after a couple of trans-atlantic
trips
with Iberia, I vowed that I would never fly with them again.
Seating was
cramped, the airport personnel were either unavailable or rude,
and the
cabin attendants were even worse. I'm not sure if smoking is
still allowed
on these flights, but I remember one 10-hour nightmare, where
no attempt
was made to accommodate passengers requests for smoking or non-smoking
seats, and the entire airplane essentially became a smoking
lounge. The
flight attendants couldn't have cared less, even seemed to cynically
enjoy
the general discomfort on board-- it gave them opportunity to
yell at
everybody!

I've spoken about Iberia with two friends of mine in Spain.
Their opinion
isn't much different from mine; they avoid it whenever possible.
